ABSTRACT:
An audio selection circuit. The audio selection circuit includes a control/switch circuit having a first input, a second input, and a first output, and a signal detector module configured to detect an audio signal on the second input. If the signal detector detects presence of the audio signal on the second input, the signal detector is configured to transmit a control signal to the control/switch circuit, and the control/switch circuit is configured in response to the control signal to disconnect the first input from the first output and to connect the second input to the first output. Otherwise, the control/switch circuit is configured to connect the first input to the first output and to disconnect the second input from the first output.
